The Airborne Information for Lateral Spacing (AILS) program at NASA Langley Research Center aims at giving pilots the information necessary to make independent approaches to parallel runways with spacing down to 2500 feet in Instrument Meteorological Conditions. The AILS concept consists of accurate tra c information visible at the navigation display and an alerting algorithm which warns the cr...

The Measurements of Pollution in the Troposphere (MOPITT) Version 6 (V6) product for carbon monoxide (CO) incorporates several enhancements which will benefit many users of MOPITT data. V6 algorithm improvements are described in detail, and V6 validation results are presented. First, a geolocation bias related to the orientation of the MOPITT instrument relative to the TERRA platform was charac...

The SEVIRI instrument on the Meteosat Second Generation satellite with both fine spatial and temporal resolution allows to detect and follow the dynamics of fast developing meteorological events like spreading smoke plumes and the lifecycles of convective clouds. Smoke plumes have the ability to change the atmospheric heat content due to 5 absorption and reduced reflection of solar radiation. B...

One of the main tools used in the TMT site testing campaign is the turbulence profiler MASS. We describe empirical investigations and a side by side comparison of two MASS systems which were performed in order to identify the accuracy of MASS turbulence data and its dependence on the instrument calibration. The accuracy of the total seeing delivered by the TMT MASS systems is found to be better...

The paired approach procedure is intended to facilitate IFR approaches to closely spaced parallel runways (closer than 2500 feet) and increase runway throughput where parallel ILS approaches cannot be conducted under instrument meteorological conditions. The paired approach procedure requires that air traffic control pair compatible and eligible aircraft and place them on the final approach cou...

There are some deficiencies in the traditional daytime visibility calculation method using CCD digital camera: visibility observation value is accurate while using the artificial objects, but expensive; nonzero internal reflection coefficient of the target lead to inaccurate visibility observation results when using natural objects as the target. A new daytime visibility algorithm based on colo...

Background: Tropospheric ozone is difficult to retrieve from satellites because of the abundance of ozone in the stratosphere. Tropospheric ozone has become a significant environmental issue and can be exacerbated by UT/LS folding and longrange transport events. Ozone can be moved from the stratosphere to the troposphere by upper tropospheric meteorological events. The Ozone Monitoring Instrume...

The objective of NASA’s Small Aircraft Transportation System (SATS) Concept of Operations (ConOps) is to facilitate High Volume Operation (HVO) of advanced small aircraft operating in nontowered non-radar airports. Given the safety-critical nature of SATS, its analysis accuracy is extremely important. However, the commonly used analysis techniques, like simulation and traditional model checking...
